9a3bbe8fc5 [test] Introduce a unit test helper to create a valid mempool transaction. (Amiti Uttarwar)
Pull request description:
Some miscellaneous improvements that came up when working on #21061
- The first commit is a helper to make valid mempool transactions & submit via ATMP. Introducing in this PR, using in #21061.
- The second commit is a small improvement in `miner_tests.cpp` that uses `BOOST_REQUIRE_EQUAL` to properly terminate the program instead of segfaulting in the failure scenario where the blocks do not include the expected number of transactions.
- The third commit changes the function signature of `GetMockTime()` to return a chrono type.
- The fourth & fifth commit overload `SetMockTime` to also accept chrono type, and adds documentation to indicate that the `int64_t` function signature is deprecated.

Add a check that new connections from the test framework to the
node have the correct user agent string. This makes bugs easier
to detect if the user agent string ever changes.

fd0be92cff doc: Add instructions on how to fuzz the P2P layer using Honggfuzz NetDriver (practicalswift)
Pull request description:
Add instructions on how to fuzz the P2P layer using [Honggfuzz NetDriver](http://blog.swiecki.net/2018/01/fuzzing-tcp-servers.html).
Honggfuzz NetDriver allows for very easy fuzzing of TCP servers such as Bitcoin Core without having to write any custom fuzzing harness. The `bitcoind` server process is largely fuzzed without modification.
This makes the fuzzing highly realistic: a bug reachable by the fuzzer is likely also remotely triggerable by an untrusted peer.
Top commit has no ACKs.

de85af5cce test: store subversion (user agent) as string in msg_version (Sebastian Falbesoner)
Pull request description:
It seems more natural to treat the "subversion" field (=user agent string, see [BIP 14](https://github.com/bitcoin/bips/blob/master/bip-0014.mediawiki#Proposal)) of a node as pure string rather than a bytestring within the test framework. This is also suggested with the naming prefix in `msg_version.strSubVer`: one probably wouldn't expect a field starting with "str" to be a bytestring that needs further decoding to be useful. This PR moves the encoding/decoding parts to the serialization/deserialization routines so that the user doesn't have to bother with that anymore.
Note that currently, in the master branch the `msg_version.strSubVer` is never read (only in `msg_version.__repr__`); However, one issue that is solved by this PR came up while testing #19509 (not merged yet): A decoding script for binary message capture files takes use of the functional test framework convert it into JSON format. Bytestrings will be convered to hexstrings, while pure strings will (surprise surprise) end up without modification in the file.
So without this patch, we get:
```
$ jq . out.json | grep -m5 strSubVer
"strSubVer": "2f5361746f7368693a32312e39392e302f"

"strSubVer": "2f5361746f7368693a32312e39392e302f"
```
After this patch:
```

std::chrono::system_clock.time_since_epoch and time_t(0) are not guaranteed
to use the Unix epoch timestamp, but in practice they almost certainly will.
Any differing behavior will be assumed to be an error, unless certain
platforms prove to consistently deviate, at which point we'll cope with it
by adding offsets.
Do a quick runtime check to verify that
time_t(0) == std::chrono::system_clock's epoch time == unix epoch.

If Boost is not found via AX_BOOST_BASE, we don't actually stop
configuring, only a warning is emitted:
```bash
checking for boostlib >= 1.58.0 (105800)... configure: We could not detect the boost libraries (version MINIMUM_REQUIRED_BOOST or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option. If you are sure you have boost installed, then check your version number looking in <boost/version.hpp>. See http://randspringer.de/boost for more documentation.
```
Instead we would usually fail when one of the other
AX_BOOST_* macros fails to find a library. These macros are slowly being
removed, and in any case, it makes more sense to fail earlier if Boost
is missing.
If Boost is unavailable, the failure now looks like:
```bash
checking for boostlib >= 1.58.0 (105800)... configure: We could not detect the boost libraries (version 1.58.0 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option. If you are sure you have boost installed, then check your version number looking in <boost/version.hpp>. See http://randspringer.de/boost for more documentation.
configure: error: Boost is not available!
```
Note that we now just pass the version into AX_BOOST_BASE, which fixes
it's display in the output (rather than MINIMUM_REQUIRED_BOOST).
This package is currently installed as a side-effect of installing our
other libboost-*-dev packages. However as those continue to dissapear,
it makes sense to install boost dev explicitly.

Performing a series of link checks for a Boost component that is
header-only doesn't make much sense, and currently means we just have
another confusing Boost macro in our tree. I'm not sure why this was
originally done this way; maybe Sjors or luke-jr can elaborate
(#15382 (929cda5470))?
The macro also has the side-effect of producing confusing error
messages. i.e in #20744, the CI is currently failing with:
```bash
checking for boostlib >= 1.58.0 (105800) lib path in "/tmp/cirrus-ci-build/depends/x86_64-pc-linux-gnu/lib"... yes
checking for boostlib >= 1.58.0 (105800)... yes
checking whether the Boost::Process library is available... yes
configure: error: Could not find a version of the Boost::Process library!
```
This isn't useful, given there is no such thing as a `Boost::Process`
library.
This PR just removes the macro entirely, but maintains a `--with-boost-process`
(defaulting to off), flag to configure. Hopefully this will also be
removed, in favour of `--enable-disable-external-signer` if/when #16546
is merged.
If the miner code is faulty and does not include any transactions in a block,
the code segfaults when it tries to access block transactions. Instead, add a
check that safely aborts the process.

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
This change proposes logic for activating UTXO snapshots, which is unused at the moment aside from an included unittest. There are a few moveonyish/refactoring commits to allow for halfway decent unittests.
Basic structure is included for specifying and checking the assumeutxo hash values used to validate activated snapshots. Initially I had specified a few height/hash pairs for mainnet in this change, but because of the security-critical nature of those parameters, I figured it was better to leave their inclusion to a future PR that includes only that change - my intent being that reviewers will be more likely to verify those parameters firsthand in a dedicated PR.
Aside from that and the snapshot activation logic, there are a few related changes:
- ~~allow caching the `nChainTx` value in the CCoinsViewDB; this is set during snapshot activation. Because we don't necessarily have access to the full chain at the time of snapshot load, this value is communicated through the snapshot metadata and must be cached within the chainstate to survive restarts.~~
- break out `CreateUTXOSnapshot()` from dumptxoutset. This is essentially a move-only change to allow the reuse of snapshot creation logic from within unittests.
- ...and a few other misc. changes that are solely related to unittests.
The move-onlyish commit is most easily reviewed with `--color-moved=zebra`.

Pull request description:
Fixes#20934 by using the "sync up" method described in https://github.com/bitcoin/bitcoin/issues/20538#issuecomment-738791868.
After improving robustness with this approach (commits 1-3), it turned out that there were still some fails, but those were unrelated to zmq: Out of 500 runs, 3 times `sync_mempool()` or `sync_blocks()` timed out, which can happen because the trickle relay time has no upper bound -- hence in rare cases, it takes longer than 60s. This is fixed by enabling immediate tx relay on node1 (commit 4), which as a nice side-effect also gives us a rough 2x speedup for the test.
For further details, also see the explanations in the commit messages.
There is no guarantee that the test is still not flaky, but it would help if potential reviewers would run the following script locally and report how many runs failed (feel free to do less than 1000 runs, as this takes quite a long if ran with `--valgrind`):
```
#!/bin/sh
OUTPUT_FILE=./zmq_results
echo ===== repeated zmq test ===== > $OUTPUT_FILE
for i in `seq 1000`; do
echo ------------------------
echo ----- test run $i -----
echo ------------------------
echo --- $i --- >> $OUTPUT_FILE
./test/functional/interface_zmq.py --valgrind
if [ $? -ne 0 ]; then
echo "FAILED. /o\\" >> $OUTPUT_FILE
else
echo "PASSED. \\o/" >> $OUTPUT_FILE
